MQTT Broker, yes. Node Red, no. You CAN use a cloud MQTT broker service for this but that isn't very Hubitat everything local. I run a very simple mosquitto MQTT broker on my NAS. Others run them on RasPi, etc. Completely understand if you don't want to do that. Just offering I'm betting there isn't a WHOLE lotta work to convert my drivers for this setup considering they are both garage doors.
